Trimethylaminuria (TMAU) is a rare genetic disorder that is caused by mutations in a specific gene. This causes the body to fail to break down the chemical compound trimethylamine. Trimethylamine is what causes a strong fishy smell, and when built up in the body is released in excretions via the sweat, urine and breath.

People with TMAU should avoid foods that contain trimethylamine. These include wheat germ, eggs, legumes, saltwater fish, and organ meats such as livers, brains, and hearts. Most patients who make these dietary changes notice drastic improvements in their body odor.
